import { type Deep } from "https://deno.land/x/rimbu@1.2.0/deep/internal.ts";
const { Protected } = Deep;
A deep readonly typed version of given type T. Makes all properties or elements read only. It maps types using the following rules:
- arrays and tuples become readonly counterparts, and all element types are wrapped in
Protectedif applicable - Maps of key type K and value type V become Maps of key type
Protected<K>and value typeProtected<V> - Sets of element type E become Sets of element type
Protected<E> - Promises of value type E become Promises of value type
Protected<E> - Objects that have only simple properties (no functions or iterators) will have all the properties as Protected if applicable
- Any other type will not be mapped
